Title: Extendable manufacturing platform in virus purification and high-purity viral vectors for use in gene therapy
Inventor: JOHN FRASER WRIGHT
IPC: A61K31/7088
Filed: 2017-09-27
Abstract: PROBLEM TO BE SOLVED: To provide methods for preparing high purity recombinant AAV vector formulations for use in gene therapy protocols.SOLUTION: An exemplary purification scheme comprises harvesting cells transduced with AAV; concentrating the cells via tangential flow filtration; and lysing the cells by microfluidization to form a lysate. The lysate is then filtered and clarified. Following clarification, the AAV particles are purified by ion exchange column chromatography and optionally further concentrated by tangential flow filtration. The eluate so generated is then added to an isopycnic gradient and subjected to ultracentrifugation, the layer containing the viral particles is harvested and subjected to buffer exchange by tangential flow filtration. The purified AAV particles are then formulated with a surfactant and the resulting formulation is filtered to remove any remaining impurities.SELECTED DRAWING: Figure 2

Title: Vehicle pillar structure
Inventor: TANAKA KEN
IPC: B60R21/213
Filed: 2017-12-01
Abstract: To obtain a vehicle pillar structure which can achieve downsizing of a pillar cross section and occupant protection at the same time.SOLUTION: A side curtain airbag 88A is fixed to a second pillar inner panel 40 by a CSA cover 96. The CSA cover 96 has a deformation part 96B which enables plastic deformation. Thus, during a vehicle collision, when an occupant collides with a rear garnish 86, a buffer load is transmitted from the rear garnish 86 to a side curtain airbag 88A, however, at that time, the buffer load is transmitted to the deformation part 96B filling a gap between the side curtain airbag 88A and the second pillar inner panel 40 and the deformation part 96B plastically deforms. Action causes the buffer load to be absorbed. Therefore, an impact received by an occupant can be alleviated without providing impact absorption parts at the second pillar inner panel 40 and the rear garnish 86 separately. Thus, downsizing of a pillar cross section and protection of occupants can be achieved at the same time.SELECTED DRAWING: Figure 4
